Delhi ki hawa ka quality Wednesday ko pehli baar iss season mein ‘severe’ category mein chala gaya, jab Air Quality Index (AQI) 418 tak pahunch gaya. Yeh sudden spike pollution level mein health aur safety ko lekar chinta bada raha hai.
Tuesday ko Delhi ka 24-hour average AQI,
jo roz 4 pm per record kiya jata hai, 334 tha, jo pehle se hi kaafi kharab tha. Lekin Wednesday ko subah 9 baje AQI reading 366 thi, jo ‘very poor’ category mein tha aur din mein severe limit ko cross kar gaya.
AQI scale per zero se le kar 50 ‘good’ air quality ko dikhata hai, 51 se 100 ‘satisfactory’, 101 se 200 ‘moderate’, 201 se 300 ‘poor’, 301 se 400 ‘very poor’, aur 401 se 450 ‘severe’ category mein aata hai. 450 ke upar readings ‘severe plus’ ka indication deti hai, jo extremely hazardous conditions ko represent karti hai.
Central Pollution Control Board (CPCB) ke data ke mutabik, Delhi ke 36 monitoring stations mein se 30 ne ‘severe’ air quality report ki. Ye widespread spike pollution mein vehicles, construction dust, aur pass ke states mein crop burning ke badhte emissions ko dikhata hai.
Winter ke aane se hawa aur bhi kharab hone ka chance hai kyunki thandi temperature aur low wind speed pollution ko ground ke paas hi trap karte hai, jisse air quality aur bhi down ho jati hai. Experts ka kehna hai ki jab tak pollution control ke liye strong steps nahi liye jayenge, Delhi ko bar bar aise air quality issues face karne padenge.
